ELECTRODE FOR ELECTROLYTIC DECOMPOSITION APPARATUS.

To all whom it may concern-N Be it known that I, CARL'FREDRIK HOLM-BO'E, a subject of the King of Norway, residing at Villa Solheia, R-iis,near Christiania, Norway, have invented certain new and usefulImprovements in Electrodes for Electrolytic Decomposition Apparatus;and'I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked "thereon, which form a part of this specification.

The present invention has for its object to provide an electrode for usein electrolytic decomposition apparatuses. Theelectrode is of the kindwhich is provided with substantially vertically disposed ribs butdistinguishes from prior electrodes of this kind in that it is built upof ribs of sheet, material which" are spaced apart from one another bysuitable intermediate spacing pieces.

- The invention is illustrated in the accompanying drawing which showsan electrode constructed in accordance with the inven tion.

Figure 1 of the drawing is a vertical sectional viewof a pair ofelectrodes suspended in the cover of an electrolytic cell.

Figure 2 isa horizontal top View partly in section oft'he same pair ofelectrodes.

In the example shown the electrodes have the shape of a lattice, thinsheet strips (3) of iron or other suitable material being .thrcaded upona number of bolts The distance between the thin sheet strips \(3) isfixed by tubular spacers (2), which are threaded upon the boltsalternatelywith the sheet strips. provided with suitably dimensioned endpieces (4) threaded on the bolts 1 and which are pressed towards eachother by means of nuts on the bolts.

The ends of the electrodes are Application filed July 23, 1924. SerialNo. 727,659.

The current is supplied-to each electrode by means of a conductor 10having an end portion formed into a sleeve 6 which is threaded onto oneof the bolts 1 between two of the ribs 5 as shown in the drawing. lhiseffects a good and reliable connection and also serves to reinforce theelectrode.

The ribs may be placed opposite each 7 other (as shown at a) or in sucha manner that the ribs of one electrode are staggered with respect tothe ribs of the other electrode, as shown at 1).

Between the electrodes 3, 3 a diaphragm 9 is arranged as shown 'in thedrawing, said diaphragm being attached to the cover 7, 8 of theelectrolyzer.

Claims:

1. An electrode for electrolytic decomposition apparatus comprisingaplurality of substantially vertical ribs of sheet material, spacers forspacing such ribs apart and means for binding said ribs and spacerstogether.

2. An electrode for electrolytic decomposition apparatus comprising aplurality of substantially vertical ribs of sheet material, spacers forspacing said ribs apart, and screw bolts for clamping together said ribsand spacers into a complete structure.

3. An electrode for electrolytic decomposition apparatus comprising aplurality of substantially vertical ribs of sheet material, spacers forspacing said ribs apart, a sleeve interposed between two adjacent ribs,a conductor electrically connected with said sleeve, and means foruniting the parts into a complete structure.

In testimony that I claim the foregoing as my. invention, l[ have signedmy name in presence of two subscribing witnesses.
